Application filed September To @ZZ 107mm t may concern ne it known thatl, EMERY F. CALIFF, a citizen of the United States of America, residing`at Detroit, in the county of Vilayne and State of Michigan, haveinvented certain new and useful Improvements in Motor-Vehicle Locks, ofwhich the following is a specification, reference being had therein tothe accompanyingT drawings.

his invention relates to locking devices adapted to control the supplyof fuel to en* ,eines of motor vehicles for thepurpose of preventing theunauthorized use of the vehicle, and its object is to provide a simpleand compact construction which may be cheaply manufactured and readilyinstalled upon motor vehicles as they are commonly constructed.

A further obj ect is to provide a construction wherein the means forcontrolling the flow of fuel performs the function of a lock therebyobviating the necessity for a key operated lock or other separate anddistinct locking means, and also to arrange the controlling means sothat members thereof may be operated. independently to functionsimilarly to rotatable members of a combination lock. lt is also anobject of the invention to provide certain other new and useful featuresin the construction, arrangement and combination of parts, all ashereinafter 'more fully described.

lilith the above and other ends in view, the invention consists indirectly controlling the llow of fuel by the interposition in the lineof ow, of independently operable members, and also consists in othermatters hereinafter more fullyset forth and parta ularly pointed out inthe appended claims, reference being had to the accompanying drawing, inwhich- Figure l is a sectional sideelevation of a portion of a motorvehicle illustrating the application thereto of a device embodying theinvention;

Figa 2 is a transverse yvertical section through the device; f

Fig. 3 a' section substantially upon the line X of'Fig. 2, and

l a plan view of the bottom half of the device showing the gear membersin place thereon;

l/Vhile the locking or controlling device embodying the invention hasbeen shown in the accompanying drawing as embodied in a particularconstruction, it will be under- Specication of Letters 'Eatent PatentedJuly i2 @ft2/il.,

stood that the construction shown is merely illustrative of theinvention and that changes may bemade therein without departing' fromthe spirit of the invention.

Further, the locking or controlling' device has been shown in Fig'. l ofthe drawing' as inserted in the gasolsne supply line adjacent thecarburetor A which is connected by a manifold B to the engine@ in theusual manner, but it will be understood that this device may -be appliedto a motor vehicle at any convenient point in the gasolene supply lineto control. the flow of gasolene to the carbureter. y

As shown in detail in the accompanying' drawing, thelocking orcontrolling device comprises a rectangular block or casing made up of alower part l and an upper part 2 which parts are recessed in theiradjacent faces to provide a chamber for gear' members, hereinafterdescribed. rl`he chambered blocks or parts l and 2 are secured togetherin any vsuitable manner as by bolts or rivets 3 so that they can not bereadily taken apart, and within the chamber l formed between theadjacent faces of the blocks, are placed disks 5 and 6 which arerotatable upon a pin Z set in bearing,f recesses in theV faces of theblocks. rllhese disks 5 and 6 are of such width that they fit closelybetween the adjacent inner faces of the blocks and are in close contactwith each other and with said faces, and an inlet channel 8 is providedin the upper part 2 of the block or casing by boring` laterally inwardfrom one side of the block transversely of the disks 5 and 6 and abovethe same, or otherwise forming or providing a passage in the top part ofthe casing, to the outer end of which passage the fuel pipe 9 leadingfrom the fuel supply (not shown) is connected. of this passage 8 extendsdownwardly and opens through the inner face of the block against whichface the disk 5 contacts. The inner end of this passage 8 opens throughthe face of the wall at a point adjacent the periphery of the disk 5 andan outlet passage l0 opens through the opposite ror forward side of theblock with its inner end openingthrough' the inner face 'of the lowerhalf l of the lblock directly opposite the inner end of the passage 8.ln the disks 5 and 6 are transverse openings ll and l2 respectively,which are so located that upon turning of the disks upon their axis 7,these openings rlhe inner end be brought into alinement with each otherand also into alinement with the passages 8 and 10, as shown in Fig. 3.

To the outer end of the passage 10 a pipe 18 is connected leading to thecarbureter A and this pipe, if found desirable, may be ljacketed asindicated in Fig. 1, so that it may not be readily'severed ordisconnected and permit of by-passing the shut-off device by connectingthe pipe 9 with the carbureter by means of a rubber tube or othersuitable connection. To rotate the disks 5 and 6 so that the openingstherein may be brought out o f alinement with 'the passages 8 and10 andthus shut off the flow of fuel therethrough, said disks are providedwith peripheral gear teeth 24C, and supported within an adjacent chamber14 of the block or casing are suitable gears 15 and 16 in mesh with theperipheral gear teeth 24 of the disks 5 and 6. The gear 15 is securedupon a tubular stem 17 and the gear 16 is secured upon a rod erstem 18extending upwardly through the sleeve 17. Upon the upper end of'thesleeve 17 is a disk 19 and adjacent thereto is a like disk 20 secureduponthe rod 18. Upon the peripheries of these 'disks are numbered linesor markings, as indicatedY at 21, so that each of the gears 15 and V16may be turned independently of the other by means of these indicatingdisks or dials 19 vand 20, which may be set upon their sleeve and rod sothat when certain 'numbers' are opposite each other, the disks 5 and 6will be turned to a position to bring the openings 11 and 12 intoalinement with eachother and with the fuel passages, and permitvthe'fuel to flow through Y Vthe casing.

GbViOuSly, any desired number of shutofi:l disks may be employed insuperposed relation and independently rotated 'in any suitable manner,the independent turning of these disks serving the purpose of rotatablemembers of -a combination lock, and thus, while the disks 5 and 6perform the function of opening and closing the fuel passage, theylalsoperform the function of a lock in Y. that they are concealed within thecasing andy their relative position must be known before they can beturned to bring their openings 11 and 12 into alinement with each otherand with the fuel passage.

v As a simple and convenient means for turning the disks 5 and 6, thegears 15 and 16, with their sleeve and rod and indicating dials, areshown, but it is obvious that any other suitable means for turning thedisks and indicating their position, may be employed. By locating theblock or casing below the floor'board D, the rod 18 and its 4sleeve maybe extended upwardly through this board, thus locating the dials 19 and20 inside the dash board of the vehicle where they are accessible to theoperator, However, the casing comprising the blocks 1 and 2 may belocated at any convenient point within th'e'fuel supply line and anysuit-r able indicating vmeans may be supported upon the dash or otherpart of the vehicle convenient to the operators seat, and suitableconnections provided therefrom to the gears 15and 16 or thedisks 5 and6.

To prevent accidental turning` of the disks 5 and 6 during the operationof the vehicle, a set screw 22 having a head 28 for turning the same,may be provided inthe upper half 2 of the casing in a position to engageat its inner end the upper disk 5. By turning the screw inwardly, itsinner end is brought against the disk `and will thus lock the diskagainst turning and at the same time force it into firm frictionalcontact with the disk 6, which diskwill thus be seated firmly againstthe contact surface of the casing, and, when the opening 12 therein isout of alinement with the passage 10, the passage will be closed and anyleakagerpast the disk will be prevented.

What l claim is 1. In an automobile lock, the combination with a vehiclehaving a drivers compartment `and dashboard and -a fuel supply line, ofa casing within the fuel supply line forming a chamber and provided witha passage for fuel communication with the supply line and Aopening atits inner 'ends through faces of the chamber at opposite points thereof,plurality of disks in said chamber with their faces in firin conta-ct100 with the faces of the walls of the chamber v and their opposed facesin firm contactwith each other, said disks having openings thereintransversely thereof V'adapted to be alined with the fuel passage in thecasing by a turning movement of the disks, said disks being alsoprovided with peripheral teeth,

gears in the casing in engagement with the peripheral teeth on thedisks7 means for turning the gears extending from the casing to a'pointwithin the 'drivers compartment inside the dashboard, and indicatingmeans carried by said means for turning the gears, said indicating meansbeing also lo-Y cated at the inner side of the dashboard.

2. In a device of the character described, the combination of a casingforming a closed chamber and having a fuel passage in the casing withthe inner ends of the fuel passage opening through the wall of thecasing into the chamber at opposite sides thereof, a plurality of disksin the chamber in close contact with each other and with the adjacentfaces of the walls of the casing. said disks being also provided withperipheral teeth, gears in the chamber in mesh with the teeth on thedisks, 'there being'a gear for each disk, means extending through oneside of the casing and'secured 'to said gears for turning each'gearinde- 18;@V

for forcing said disks into iirm Contact With l0 each other and With aWall of the Casing.

In testimony whereof I affix my signature inthe presence of tWoWitnesses.
